In 1970, two mountaineers in Nepal were climbing at 13000 feet (4.000m) above sea level when they stumbled across a set of mysterious footprints. Later Don Williams, one of the climbers, claimed to have seen an ape like creature responsible for the prints. The Abominable Snowman (Yeti or Sasquatch) has been reported for hundreds of years yet very few people have ever seen it. Whilst myths and folklore of indigenous populations accept the existence of hairy human like creatures our scientific community remains, skeptical.
Bigfoot comes in a several varieties, the Yeti from Asia, Sasquatch from North America, and Almas of Russia, Mongolia and China. Some believe Bigfoot to be the last surviving relic of Neanderthal man which lives in the most remote parts of the world. Footprints as a means of evidence may seem solid enough and there have been plenty reported over the years. However, snow prints in the sun are easily enlarged and simple for pranksters and hoaxers to manipulate. So although over a thousand were found at Bossberg, Washington State in 1969, not much credence can be given to them.
In Bluff Creek, Carolina in 1967, Roger Patterson was thrown from his horse whilst filming the countryside. By chance he captured a few frames of what appeared to be a large ape like creature. Many people believe this is convincing evidence of the existence of Bigfoot. Unfortunately, scientific evidence disagrees. The size of the animal compared to its footprint is out of proportion. The foot size and stride length are also incompatible. Walking is a cyclic event and depending on the size and shape of our human form determines how we move. In the case of Bigfoot from the photographic evidence is inconclusive.
More compelling evidence comes from a 1917 report, of a geology expedition travelling the Venezuela/Colombian border. They came across two aggressive ape-like creatures. Terrified at their antics they shot one before the other escaped. They photographed and measured the dead creature. It was approximately 5' (1.5m), taller than any known South American primate. The head and teeth were humanoid. The photograph taken by the geologists provides vital proof unknown anthropoids may still be alive, and living in remote parts of the world.
